Math Fun Days are a weekly event we're holding to get math teachers talking, problem solving and having fun together. Participants gather in Google hangouts and work together to solve compelling problems or play math games that they can then bring to students in their classrooms. If you want to participate or have a great problem for us to solve, tweet @ one of the moderators in the sidebar.
